[arm/master] Wizard config for setting up an exit

commit e8c3836e203a3e359a9b5b9a289dc73ddc3da92c Author: Damian Johnson <atagar(a)torproject.org> Date: Mon Jun 27 08:54:07 2011 -0700 Wizard config for setting up an exit This expands the wizard to provide a config panel for setting up an exit relay. This has the same options as an internal relay plus several for DirPortFrontPage and ExitPolicy. By default this will use the reduced exit policy [1], with options like Vidalia for selecting groups of services to allow. However, unlike Vidalia it won't allow the operator to pick plaintext ports without also having their encryped counterparts.
